Hi, I want to know if there is a difference between the two hierarchical methods Agnes and hclust when there are used with the same method and the same metric on the same data! I ask this question because I executed the following program: hc <- hclust(dist(AGRIINSTTableFinaleCR), "ward") agnes<-agnes(dist(AGRIINSTTableFinaleCR),method="ward") And clusters are not the same even if they are a little similar! Is anybody know why i have this difference? Thanks in advance Nicolas BOUGET

Hi, Is there a equivalent of the function "eboulis()" (which is a new funtion on Splus) on R? Otherwise, with which function can we see the best number of cluster we have to choose? Thanks in advance, Nicolas BOUGET
